How to Properly Tie a Medical Waste Bag

Updated: Jan 23, 2023

Eliminate Possible Spills and Leaks of Medical Waste By Tying Biohazardous Bags Correctly

Every medical waste generator needs to know how to properly tie a biohazard bag after it is full. Having a properly sealed bag is one of the regulatory requirements for packaging your medical waste for transport. Believe it or not, there's a right way, and a wrong way to tie a medical waste bag once its full. The right way will mean that your bag will be less likely to leak if turned upside down.

Step 1 - Use The Overhand Knot: Gather, Twist End 8″-10″

Step 2 - Make Loop With the Twisted End

Step 3 - Loop the End Through to Create a Knot

Rabbit Ears

Often times, bags are tied in a rabbit ear fashion, which tends to leak if the box is tipped over. Therefore, tying your biohazardous bag like this is not recommended as it can potentially expose you and your team members to infectious fluids.

After tying off your infectious waste bag, please ensure your self sealing box or container lid is securely closed. Make sure that you don’t have any loose sharps in your biohazard bag or medical waste transport container. All sharps belong in a puncture-resistant red sharps box before going into the medical waste container. Sharps include needles, syringes, broken glass, scalpels, capillary tubes, culture slides, broken rigid plastic and exposed wires. This step will ensure safety for both your team and ours.
